GOOS-Brazil

The deployment of drifting buoys and moorings by PNBOIA has improved the knowledge and contributed to the elaboration of oceanographic, climatological and meteorological forecasts, necessary for assessing how to better explore the oceans' resources.

From the beginning of its activities PNBOIA already deployed 40 drifters, from which 10 are still working, e 2 moorings. The data collected from these buoys are transmitted in real time through satellite to the climate and weather prediction centers and to the scientific community.

Another important component of our monitoring system is PIRATA. This is a multinational effort involving Brazil, France and the Unites States. PIRATA has 12 moorings in the tropical Atlantic with sub-surface sampling of temperature and salinity to the depth of 500m. This information is also important to improve the predictability of climatic anomalis in the north and northeast regions of Brazil. In 2005 the array of the original PIRATA backbone was extended to the southwest with an addition of 3 more buoys.

The GLOSS-BRAZIL project is the Brazilian counterpart for the international program GLOSS for monitoring the variations of the mean sea level in the coastal regions. Currently there are 12 stations along the Brazilian coast.

From 2005, Brazil participates in the international project Argo contributing with the deployment of 3 drifters in the South Atlantic.
